Watch port

The clock port of the Amiga 1200 was originally intended to receive a real-time clock that continues to run on battery power even when the computer is switched off.

However, since this function was already built into all processor cards of the Amiga 1200, this was only rarely implemented. In the absence of internal slots in the keyboard housing of the Amiga 1200, this interface was used by developers for special serial cards , USB cards and sound cards . Later "clock ports" were built on internal cards for the Amiga 600, 2000, 3000 and 4000. Thus these expansions could be used without occupying additional internal slots.
